[0002] Coal mine roadway driving is a comprehensive engineering operation process, which involves multiple links and the comprehensive use of technology. In coal mining, roadway driving is the key step to obtain coal resources, build mine ventilation systems, transportation systems, and personnel access channels. This process not only requires efficient driving equipment such as driving machines and rock drills to break and excavate rock or coal seams, but also requires reasonable support technology such as anchor support and shed support to ensure the safety and stability of the roadway. At the same time, during the driving process, the construction of supporting facilities such as ventilation, drainage, and transportation, as well as the safety training and protection measures for operating personnel, need to be considered.
